≈ $31.6M–$123.4M after Steam's cut

All 3 of the similar games are hits.

This comes from a small set of games, so take it as a sketch.

The genre you'd be entering

These games: The similar games share Sandbox (3 of 3) and Simulation (3 of 3).
The winners: Winners here lead with Space + Grand Strategy, priced around $50.
When they shipped: None of the similar games shipped in the last two years; the newest is from 2019. That says more about which games were found than about the market.

How these numbers were worked out

A hit here: 1,000+ reviews, roughly $150k+ before Steam's cut (a standard indie benchmark).

Copies come from each game's reviews times a sales-per-review rate that falls with release age, from about 36 for the most recent game here to about 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
